The app will show you a (very nice) visual representation of all of the zodiac signs: Pisces, Gemini, Taurus, Aries, Libra, Virgo... you just have to tap on one of them to access all the information about it.
The information about each zodiac sign includes information about love, work, friendship, compatibility with other signs, and much more. You can also view some of the celebrities who have the same sign.
Anyway, the best thing about Horoscope is that it offers all of this information using an intuitive interface with an attractive visual style, something that other, similar apps do not usually do.
Horoscope is a good horoscope app that people who believe in this kind of thing will most definitely love.
Requires Android 1.6 or later.
